Soff-Cut saws are a great tool to eliminate the chance of cracking in green concrete. These early entry saws need to be set up and maintained properly to maximize your efficiency. Jack Tuckner, one of Esch's Soff-Cut experts, explains what you should do before running your Soff-Cut saws:
Soff-Cut Saw Setup and Maintenance
1. Make sure the blade block pistons are moving freely.
The pistons should freely move up and down when you press up on them. If it's jammed, there might be bits of concrete stuck inside the blade block. If the blade block pistons are still jammed, use a graphite-based lubricant (do not use WD40)
2. Align the Soff-Cut Blade with the Skid Plate
The skid plate is designed to keep the Soff-Cut blade stable when cutting a joint. If the skid plate is bent, the Soff-Cut blade will wobble when it's cutting, causing ravelled Soff-Cut joints. Replace your skid plate if it is bent or damaged.
3. Add a vacuum
4. Make sure you are in the Green Zone
The Green Zone is the window of opportunity to cut the concrete before it has a chance to crack. Test the concrete by touching, stepping, and rolling the Soff-Cut Saw onto the concrete. If there are no impressions on the concrete, you are ready to begin laying out your cuts.
5: Break in your Soff-Cut Blade
Every time you use a new Soff-Cut blade, you should break it in. To break in your Soff-Cut blade, set your saw to 50% rpm, run your saw & blade for 30ft. After 30ft your Soff-Cut blade should be properly broken in. The diamonds in the segment are more exposed to the concrete which allows for faster, smoother cutting.
